Problems solved by technology
At present, radar dynamic organization methods are mostly aimed at each fusion processing level of multi-radar, and the relationship between different factors is separated, and radar station layout or radar parameters or fusion methods are designed separately. This method is incomplete for the design of multi-radar system resources. , cannot well adapt to the needs of complex environments and targets

Embodiment Construction
[0071] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.
[0072] In an embodiment of the present invention, consider an observation system with N radars spontaneously sent and received, and a multi-radar dynamic adjustment method based on information entropy, such as figure 1 As shown, specifically:
[0073] S1. Receive initial observation data from multiple radars. In this embodiment, the initial observation data may be the echo sequence of N radars to the same target, the target trace after detection, or the extracted feature vector.
[0074] S2. Obtain a pre-established observation fusion model, and establish a multi-radar fusion entropy model based on the observed fusion model.
[0075] Specifically, for the fusion process of target detection, tracking, and recognition, a generalized model of multi-radar observation decision-making is established uniformly, which is formula (3):

An embodiment of the invention relates to a multi-radar dynamic adjustment method and a multi-radar dynamic adjustment device based on information entropy. The multi-radar dynamic adjustment method comprises the steps of: S1, receiving initial observation data of a plurality of radars; S2, acquiring a pre-established observation fusion model, and establishing a multi-radar fusion entropy model according to the observation fusion model; S3, optimizing the multi-radar fusion entropy model; S4, and adjusting radar positions of the plurality of radar, parameters of each radar and an observation data fusion method according to an optimization result. The multi-radar dynamic adjustment method can be based on operational missions of different levels, and optimizes and adjusts the radar station distribution, radar parameters and the fusion method in a self-adaptive manner, so as to adapt to dynamic changes of a battlefield environment and a target, thereby achieving the purpose of maximizing the target information.
Description
Technical field [0001] The invention relates to the technical field of radar system resource management, in particular to a method and device for dynamic multi-radar adjustment based on information entropy. Background technique [0002] In practice, the battlefield environment and targets are constantly changing. According to combat missions, it is necessary to dynamically organize multiple radar system resources, including radar stations, radar parameters, and fusion methods, to adapt to the ever-changing complex environment and targets. Maximize the acquisition of target information and achieve the best target detection, tracking or recognition. [0003] The geographic location or radar parameters of the radar relative to the target are different, the target information obtained will be different, and the accuracy of the result will be different if different fusion methods are used. Moreover, for multi-radar observation decision-making, the influence of these factors is coupled....
